At over 40 measuring points, the flow rate is determined from the damming height above a Venturi constriction. The water level, the calculated flow rate, the summed daily total and information on the maintenance of the measuring point are recorded by Microtronics. With myDatalog, this data is sent via GPRS to the central server at ARA Thunersee. In this way, the staff of ARA Thunersee can read out the data from the measuring points at any time via remote access. The project coordination and the installation of the remote access solution were carried out by the Swiss company Imeth AG, which is also responsible for its maintenance.
